Preheat oven to 350°F (177°C). Line a large baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, combine oats and applesauce. Stir with a spatula until all the oats are coated in applesauce and the ingredients are evenly mixed. Stir in the raisins until they are evenly incorporated. Your dough will be very wet and loose. This is normal.
Using a 1.5 tbsp cookie scoop, scoop cookie dough and release onto your prepared baking sheet, spaced 1.5 inches apart. Use the palm of your hand to press down on each cookie dough ball so that it forms a thick round disk. You may need to shape the sides of the cookie with your hands to make them round. Cookies will not spread during baking so you want to shape the cookies to how you want the final product to be.
Bake cookies for about 15 minutes. Let cookies cool on baking sheet. Once cookies are cooled, remove cookies using a thin cookie spatula. Store uneaten cookies at room temperature for 1-2 days or longer in the fridge or freezer.
Notes
I made these cookies with unsweetened applesauce. If you like cinnamon in your oatmeal cookies you can use unsweetened cinnamon applesauce or add 1/2 tsp of cinnamon to your batter.
8 oz of applesauce refers to the weight.
I chopped the raisins so that they can be more evenly distributed in the cookies. You can also add chopped nuts.
